Main

Patrick Cherry

PhD scientist skilled in bioinformatics, biological data science, statistical modeling, next-generation sequencing (NGS), and tool-building. I’ve coded high-throughput experimental designs and genomic analyses, launched best-in-class oncology reference standards, and invented new molecular methods for DNA and microbe manipulation. Originally trained in Molecular Biology, I’m interested in taking my knowledge and practice of data science and bioinformatics to the next level.

Senior Scientist

Twist Bioscience

South San Francisco, California

Current - 2022

  • Tech Lead of multiple reference control NPIs, custom OEM projects, and commercial release OEM. Includes the Pan-cancer RNA Fusion Controls, Fragmentome Calibration Standards, CNV Controls, Pan-cancer cfDNA v2, and RNA-seq.
  • Mentored a direct report from Senior Research Associate to Scientist to serving as a Tech Lead on new product introductions
  • Original research led to multiple outside presentations and applications for patent protection of product configuration and biochemical methods.
  • Custom analysis demonstrated proof-of-concept design and QC success of the Pan-cancer RNA Fusion Controls; designed and implemented the production approach; used public data and feedback from alpha testers to design configuration of fusions RNAs
  • Led technical evaluation of a new NGS platform with custom experiments and bioinformatic analyses to enable faster gene QC in Production. Also led ancillary experiments to speed up production. Coded, implemented, and distributed on company GitHub an internal package, twistcolorpal, that automatically adds Twist-brand colors to ggplot2 plots and sets up database connectors to SQL / Snowflake for parameterized dbplyr querying. Regularly use AWS s3 and Spark, PySpark, and Sparklyr, locally and on Databricks.

Trainees & Direct Reports

While I’ve not held a role with a “manager” title, all Scientist positions I’ve accepted have had formal report management responsibility. I take managing and mentoring seriously and emphasize trust, learning, and growth with my reports.
